ANNUAL REPORT OF THE 



REPORT ON THE ZOOLOGICAL LABORATORY. 



By E. L. Mark. 



Aside from the changes due to the regular alternation of certain 

 courses, the courses of instruction in Zoology during 1910-11 were 

 substantially the same as in 1909-1910, with one exception — the 

 addition of Zoology 7d, Forest Entomology. Merely formal 

 changes were, the substitution of "Practical Entomology" for 

 "Common Economic Insects and Methods of controlling them" 

 as a description of Zoology 7c, and the designation by new mem- 

 bers of two of the fields of research previously offered: "206, 

 Cytology, with special Reference to Heredity," and "20g, Experi- 

 mental Morphology." 



As usual, the following tables show the number of students in 

 each of the several classes who attended each of the courses in 

 Zoology. The first table exhibits the facts for Harvard University,, 

 the second for Radcliffe College.
